The previous memory allocation procedures tried to allocate memory via `new` or `mmap` and inserted the pointer to the memory into an std::vector afterwards. In case `new` or `mmap` threw or returned a nullptr, no memory was leaking. If `new` or `mmap` worked ok, the following `vector::push_back` could still fail and throw an exception. In this case, the memory just allocated was leaked. The fix is to reserve space in the target memory pointer block beforehand. If this throws, then no memory is allocated nor leaked. If the reserve works but the actual allocation fails, still no memory is leaked, only the target vector will have space for at least one more element than actually required (but this may be reused for the next allocation) |

RocksDB: A Persistent Key-Value Store for Flash and RAM Storage
RocksDB is developed and maintained by Facebook Database Engineering Team. It is built on earlier work on LevelDB by Sanjay Ghemawat (sanjay@google.com) and Jeff Dean (jeff@google.com)
This code is a library that forms the core building block for a fast key value server, especially suited for storing data on flash drives. It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF) and Space-Amplification-Factor (SAF). It has multi-threaded compactions, making it specially suitable for storing multiple terabytes of data in a single database.

See the github wiki for more explanation.
The public interface is in include/

internal APIs may be changed without warning.
